Parameter Creation

Parameters can be used in archive files. You can specify either internal or external parameters. Internal parameters are replaced by values that are specified internally by the packaged program or the operating system. External parameters are replaced by values that are specified externally in files that are created during the installation of an SXP parameter product on the target computer.

Each parameter is replaced by the values in the following sequence:

1. The Installer checks for the parameter in the internal parameters.
2. If the parameter is not found there, the Installer checks for it in the external parameters, which are located in special parameter files.
3. If the parameter is not found there, the Installer checks for it in the default parameter set included in the package.

The sequence in which the parameter files are searched corresponds to the sequence in which these files are specified in the Installer's configuration file.

The Installer checks the following archive files to see if they contain parameters and replaces the parameter values automatically:

• All SXP archive files
• All scripts specified in original.sxp and ascnnnn.sxp files
• All archive files specified in the #ReplaceParams# section of the files.sxp file. These archive files must be stored in the files.cmp file.
• All files specified in the #ReplaceParams# and #ReplaceParamsUNICODE# sections of the actions.sxp file. These files must not be stored in the files.cmp file.
